DownloadManager

modde_sources::manager

Struct DownloadManager 

Source 
pub struct DownloadManager { /* private fields */ }
Expand description

Manages a queue of downloads with progress tracking.

This is a synchronous data structure – callers drive the actual async downloads and update state through the provided methods.

Implementations§

Source§

impl DownloadManager

Source

pub fn new(max_concurrent: usize) -> Self

Create an empty manager allowing up to max_concurrent active downloads.

Source

pub fn enqueue( &mut self, url: String, dest: PathBuf, mod_name: Option<String>, ) -> usize

Add a download to the queue. Returns the assigned download ID.

Source

pub fn pause(&mut self, id: usize, bytes_so_far: u64)

Pause an active download, recording how many bytes were fetched so far.

Source

pub fn resume(&mut self, id: usize)

Move a paused download back to the queue.

Source

pub fn cancel(&mut self, id: usize)

Remove a download from the manager entirely.

Source

pub fn active_count(&self) -> usize

Number of currently active downloads.

Source

pub fn max_concurrent(&self) -> usize

Maximum number of concurrent downloads allowed.

Source

pub fn all(&self) -> &[ManagedDownload]

View all tracked downloads.

Source

pub fn get_mut(&mut self, id: usize) -> Option<&mut ManagedDownload>

Get a mutable reference to a download by ID.

Source

pub fn get(&self, id: usize) -> Option<&ManagedDownload>

Get an immutable reference to a download by ID.

Source

pub fn can_start_more(&self) -> bool

Returns true if there is room to start another download.

Source

pub fn next_queued(&self) -> Vec<usize>

Return IDs of queued downloads that could be activated, up to the remaining concurrency budget.
